The 21-year-old man from Monroe, who is not a student, stabbed the two students outside the fraternity house, in the 1400 block of Washtenaw Avenue, when they asked him to leave the party after an altercation, according to Ann Arbor police.

The suspect was at the party with another man and two women, police said.

Although recognized by their national office, the Sigma Alpha Epsilon fraternity is not recognized by U-M Greek Life governing boards or the U-M Office of Student Involvement, school officials said.

That's because in 2011 the fraternity was dismissed from the Interfraternity Council after allegations of hazing that included poking pledges with broomsticks, kicking them in the groin and shooting airsoft guns at them.

The local fraternity was also suspended by its national fraternity office, although that sanction has since been lifted.

The students stabbed Friday are expected to recover from what were described as minor wounds, police said.

The suspect is in police custody and is expected to be arraigned for felonious assault.
